Thermal compensation for a holographic beam forming antenna

A holographic metasurface antenna (HMA) that compensates for temperature, comprising:

• an array of scattering elements that are dynamically adjustable in response to one or more waves provided by the one or more wave sources;
• a computer, including:
• a memory for storing instructions;
• one or more processors that execute the instructions that are configured to cause actions, comprising:
• providing a first holographic function to the HMA to produce a first object wave that radiates a first beam;
• monitoring one or more operating temperatures of the HMA with one or more temperature sensors;
• monitoring one or more behaviors of the HMA, wherein the monitored behaviors are compared to a characterized range of normal behaviors for the first holographic function;
• in response to one or more of a current operating temperature of the HMA is identified as outside a range of normal operating temperatures, or a current behavior of the HMA is identified as abnormal behavior, performing further actions, including:
• providing a second hologram function to produce a second object wave to radiate a second beam that is equivalent to the first beam;
• and
• providing a plurality of hologram functions that are used to produce corresponding object waves that radiate associated beams;
• and
• for each of the plurality of hologram functions, performing actions, including:
• producing a corresponding object wave to radiate an associated beam while operating the HMA at each of a range of characterization temperatures having a minimum temperature that is less than a predicted range of normal operating temperatures and a maximum temperature that is greater than the predicted range of normal operating temperatures;
• identifying operation of the HMA at each characterization temperature as normal behavior or abnormal behavior;
• and
• characterizing a particular range of normal operating temperatures based on each characterization temperature that is associated with normal behavior in the operation of the HMA to radiate the associated beam.
